HENRY M. HENRY, OF ST. LOUIS, MISSOURI.

SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 412,612, dated October8, 1889.

Application filed May 21, 1889.

To all whom it may concern:

Be it known' that I, HENRY M. HENRY, a citizen of the United States,residingat St. Louis, in the State of Missouri, have invented certainnew and useful Improvements in Spring Bed-Bottoms, of which thefollowing is a specification, reference being had therein to theaccompanying drawings, in which- Figure l represents a plan view of aportion of my improved spring-bed; Fig. 2, a detail perspective view ofa portion thereof, and Fig. 3 a detail side elevation of a modification.

The invention relates to that class of bedbottoms wherein thecoil-springs are arranged and secured in series in a vertical positionfor the support of the mattress.

The object of the present invention is to provide an exceedingly simpleand strong arrangement of intersecting twisted tie-wires,

- whereby the springs will be effectually prevented from shiftinglaterally without impairing to any appreciable extent the resiliency ofthe same, as will be more fully hereinafter set forth.

In the drawings annexed, A A designate, respectively, the top and bottomframes of the bed-bottom, and B the double conical spiral springssecured to the said frames.

My improved tie-wires C each consist of two strands of strong stout wiretwisted together the greater part lof their length and secured at theirends to the side bars of the frames. One of these tie-wires C is passedboth transversely and longitudinally of the bed-bottom between each rowor series of springs, the twisted portions of the wires intersectingeach other at points about equal distances from the tops of the springs.Where the twisted tie-wires pass between the springs they are separatedand formed into oppositely.- projecting loops a a, through which theupper and lower coils of the springs pass. The tie-wires, when drawntaut, will serve to eifectually hold the springs in a perfectlyuprightposition. The bottoms of the springs are secured to the bottom frame inthe same manner as the tops of the springs are secured (No model.)

to the top frame. Auxiliary wire stays b secure the corner springs tothe frames.

When secured in the manner described, the springs will require no othersupports whatever, the twisted intersecting wires serving to supportthem without additional means.

The essential feature of the invention is that the end coils of eachspring, except the border coils, will be braced and secured at fourdifferent points, thereby precluding the possibility of the springsbecoming displaced or bent by the movements of the occupant of the bed.

Instead of attaching the ends of the staywires directly to the frames,as shown at top of Fig. 1, the parts of the stay-wires may be separated,and, after being passed or wrapped around the framebar once or twice,carried into the end coils of the springs and attached thereto, as shownat c to the left of Fig. l, thereby bracing the border springs againstlateral movement.

As shown in Fig. 3, I may use single conical springs E and attach theirlower ends to slats F, instead of employing two of the frames A.

Having thus fully described my invention, what I claim is- 1. In aspring bedbottom,the combination of a frame A, bed-springs B, arrangedin transverse and longitudinal rows within the said frame, and thelongitudinal and transverse tie-wires C, extending entirely across theframe and securely fastened to the same at their ends, these tie-wiresbeing arranged between the rows of springs, so` as to interse'ct eachother, and being constructed each of two strands of wire tightly twistedtogether, loops d a being formed by separating the strands of the tie,these loops receiving the end coils of the springs, as shown, where- .bythe entire bed of springs will be firmly connected together and to theframe, thereby preventing lateral movement of the springs in alldirections, substantially as described.

2. The combination of a frame, springs arranged in rows within theframe, and the parallel intersecting tie-wires C, Secured to said frameand composed of twisted Wire strands, In testimony whereof I ax mysignature in 1o the ends c c of these tie-wires being Wrapped presenceof two witnesses.

as described.
